Meanwhile, Ford recently appeared in 'The Expendables 3', alongside fellow Hollywood star Sylvester Stallone, who spoke about how their friendship was fostered when they were both struggling actors in the late 1970s.

He said: ''Both of us would be wondering how long this acting was gonna last. Actually we became very, very close ... Harrison is a very insulated, intelligent and very funny, very witty, dry humorist. When you tap into that, it's great.''
